But yesterday's biggest show  Jason Wu  opened with 16-year-old Daphne Groeneveld, signaling her newly minted runway must-have status. The teen has so far landed the cover of French Vogue and starred in Givenchy's latest campaign, yet Groeneveld told us she "doesn't really think of this as success just yet. It's been a great start, though." We asked if she will open for Calvin Klein again, but mum was the word: "I'm keeping that as a surprise." See who else opened and closed for Friday's biggest shows in the slideshow ahead.
